The concept of periodization in training refers to the systematic planning of athletic or physical training over specific time frames, often divided into cycles to optimize performance and prevent overtraining. By varying training intensity, volume, and recovery phases, athletes can enhance their fitness levels while reducing the risk of burnout or injuries. Periodization typically includes phases such as preparation, competition, and transition. This structured approach helps in achieving peak performance at scheduled times, ensuring athletes adapt to training stimuli effectively over time.
